Chikungunya outbreak

Mauritius is experiencing a chikungunya outbreak (CDC Level 2 alert, 2026). Chikungunya causes fever and often debilitating joint pain that can persist for months. All travelers should practice strict daytime mosquito-bite prevention; vaccination may be discussed for travelers at higher risk (see EKRM statement).

Yellow fever entry certificate

Mauritius has no yellow fever risk, but a valid YF vaccination certificate is required for travelers aged 1 year and older arriving from (or having transited >12 hours through) a country with risk of YF transmission. Direct travel from Switzerland is not affected.

Vaccines

VaccineRecommendationReference
Routine vaccines

Make sure you are up-to-date on all routine vaccines before every trip — per the Swiss BAG schedule. These include:

BAG Impfplan
Chikungunya

Vaccination indicated during chikungunya outbreaks — an outbreak is currently ongoing (2026). May be considered for travelers at higher risk for severe disease (see EKRM statement).

—
Dengue

Qdenga® vaccination currently recommended only for travelers with documented prior dengue infection who will be exposed in a region with high dengue transmission.

—
Hepatitis A

Recommended for all travelers aged 1 year and older. Note for Swiss travelers: hepatitis A is not part of the routine Swiss BAG childhood schedule, so most adult travelers will need vaccination.

CDC Yellow Book
Hepatitis B

CDC recommends hepatitis B for unvaccinated travelers of all ages. Routine in the Swiss BAG childhood schedule — younger travelers are usually already covered; older travelers can consider it per individual risk and stay duration.

CDC Yellow Book
Rabies

Consider for long stays or higher individual risk (cycling/motorbike trips, hiking in remote areas, infants and children, animal workers). Risk on Mauritius is low but post-exposure care may require travel to a larger facility.

CDC Yellow Book
Typhoid

Recommended for long-term travelers, those visiting friends and relatives, staying in rural areas or poor hygienic conditions, or with individual risk factors.

Disease-specific guidance

Malaria

None

No malaria risk. Mauritius is considered malaria-free; no antimalarial prophylaxis is needed. Mosquito-bite prevention is still worthwhile because of dengue and chikungunya.

Yellow fever

None

No yellow fever risk in Mauritius. A YF vaccination certificate is required only for travelers aged ≥1 year arriving from, or having transited >12 hours through, a YF-risk country. Direct travel from Switzerland is not affected.

Dengue

Moderate

Dengue circulates in Mauritius with year-round transmission and seasonal peaks during the warm, rainy summer months (roughly November–May). The Aedes mosquito vector bites during the day, so daytime bite prevention is the main protection for every traveler.

Distribution
Island-wide, incl. coastal resort areas
Season
Year-round; peaks Nov–May (warm/rainy)
Vector
Aedes — bites during daytime

Chikungunya

High

Chikungunya is a recurring threat in Mauritius, with a significant outbreak ongoing in 2026 (CDC Level 2). Same daytime Aedes vector as dengue, so the same bite-prevention measures apply. Joint pain can persist for months after the acute illness. Vaccination is considered in outbreak settings (see EKRM statement).

Status
Active outbreak (2026)
Vector
Aedes — bites during daytime
Symptoms
Fever + prolonged joint pain

General prevention

Food & water

Tap water in the main tourist areas and hotels is generally safe. In rural areas or if uncertain, prefer bottled or filtered water. Standard food hygiene reduces the risk of traveler's diarrhea, hepatitis A, and typhoid — particularly when eating outside major hotels and resorts.

Mosquito protection

No malaria risk in Mauritius. Daytime mosquito-bite prevention (DEET or picaridin repellent, long sleeves) is the key measure because of year-round dengue activity and recurring chikungunya outbreaks — both spread by Aedes mosquitoes that bite during the day. Avoid swimming in fresh water (schistosomiasis, leptospirosis).
